To calculate the solubility of CuBr in pure water and in a $$ 0.0110 \, \text{M} \, \text{CoBr}_2 $$ solution, we need to follow these steps:

1. **Find the $$ K_{sp} $$ value for CuBr**: This value is typically provided in the data tab. Let's denote it as $$ K_{sp} $$.

2. **Set up the solubility equilibrium**:
   - The dissolution of CuBr can be represented as:
     $$
     \text{CuBr (s)} \rightleftharpoons \text{Cu}^+ (aq) + \text{Br}^- (aq)
     $$
   - The solubility product expression is:
     $$
     K_{sp} = [\text{Cu}^+][\text{Br}^-]
     $$

3. **Calculate the solubility in pure water**:
   - Let $$ s $$ be the solubility of CuBr in mol/L. Then:
     $$
     K_{sp} = s \cdot s = s^2
     $$
   - Solve for $$ s $$:
     $$
     s = \sqrt{K_{sp}}
     $$

4. **Calculate the solubility in $$ 0.0110 \, \text{M} \, \text{CoBr}_2 $$**:
   - In this case, the concentration of Br$$^-$$ ions from CoBr$$_2$$ will affect the solubility of CuBr. The equilibrium will be:
     $$
     K_{sp} = [\text{Cu}^+][\text{Br}^- + 0.0110]
     $$
   - Let $$ s' $$ be the solubility of CuBr in this solution. Then:
     $$
     K_{sp} = s' \cdot (0.0110 + s') \approx s' \cdot 0.0110 \quad (\text{assuming } s' \text{ is small})
     $$
   - Solve for $$ s' $$:
     $$
     s' = \frac{K_{sp}}{0.0110}
     $$

Now, please provide the $$ K_{sp} $$ value for CuBr so we can proceed with the calculations.
To find the solubility of CuBr in pure water and in a $$ 0.0110 \, \text{M} \, \text{CoBr}_2 $$ solution, follow these steps: 1. **Find $$ K_{sp} $$ for CuBr** from the ALEKS Data tab. 2. **Calculate solubility in pure water**: $$ \text{Solubility} = \sqrt{K_{sp}} $$ Round to 2 significant digits. 3. **Calculate solubility in $$ 0.0110 \, \text{M} \, \text{CoBr}_2 $$**: $$ \text{Solubility} = \frac{K_{sp}}{0.0110} $$ Round to 2 significant digits. Provide the $$ K_{sp} $$ value to get the exact solubility.
